FLUORINATED GEL-EMULSIONS

New highly concentrated emulsions have been made from fluorocarbons an d nonionic fluorinated surfactants. They can contain till 98 % water a s the dispersed phase. With such a water content, they are viscoelasti c materials like gels. They are optically transparent, an original pro perty for emulsion systems. The continuous phase is water swollen mice llar phase. Their structure has been studied by small angle X-ray and neutron scattering, and correlated to rheological properties and stabi lity (phase diagrams). The parameters of interest are the chemical str ucture of the surfactants, the composition, temperature and water sali nity.
